MAYROCK LFP Battery

MAYROCK Zero Emission Commercial Vehicles combine several innovative technologies with the goal of delivering the most versatile commercial fleet solution with the longest warranty and lowest overall TCO.

Lithium Iron Phosphate (LFP) Battery from Leading Global Battery Supplier

Conventional battery-powered electric vehicles use Ternary Lithium batteries, most commonly lithium nickel manganese cobalt oxide (NMC), while MAYROCK vehicles utilize Lithium Iron Phosphate (LFP) batteries.

Advantages of LFP batteries compared to conventional NMC batteries

An LFP battery has lower energy density but compensates by offering over 2x more charging cycles. Using LFP batteries allows MAYROCK to offer an industry-leading 8 year / 150,000 mile battery warranty, significantly reducing the TCO for fleet operators.

Battery Safety

Thermal Runaway in batteries occurs when an increase in temperature causes a chain reaction that further increases the temperature of the battery, creating a fire risk. Physical impact, such as in the case of an accident, is one of the potential catalysts for thermal runaway and is of particular concern with battery-powered commercial vehicles.

LFP batteries are more stable and have a higher threshold temperature for thermal runaway (200 ºC, compared to 170 ºC for NMC batteries). This makes it harder to generate enough heat to begin the chain reaction, reducing the likelihood of thermal runaway.

MAYROCK threshold temperature

If thermal runaway does occur, LFP batteries maintain a much lower internal temperature, making them less likely to combust (maximum temperature of 400 ºC, compared to 670 ºC for NMC batteries). LFP batteries also generate less total gas/vapor during thermal runaway and much less toxic CO gas, further increasing vehicle safety.

The key minerals for LFP batteries are a great deal more abundant than minerals for nickel-based batteries, resulting in lower (and more stable) pricing. LFP batteries are currently up to 25% less expensive per kWh than nickel-based batteries, and predicted to continue dropping over the coming years as LFP energy density continues to improve. As LFP battery prices per kWh continue to drop, we will be able to pass the savings to fleet operators to promote a lower TCO.

Easy Step-In Technology

By integrating the electric motor drivetrain directly into the driving wheels, MAYROCK vehicles offer a lower step-in height and fully flat cargo floor with minimal wheel well intrusion. This makes it easier to load and unload larger packages and increases increase total cargo volume by up to 32% over traditional step vans.
